From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95/96/97. byNancy McCracken and Geoffrey C. Fox
Second order equations such as
can always be rewritten as a system of 2 first-order equations involving X and a new variable Y representing the first order derivative:
